Frequently Asked Questions About Expatriate Tax

The question of domicile under UK law is extremely multi-faceted and will need to be interpreted after analysing the laws using your unique set of facts. It’s important to do this as an expat because there may be significant tax advantages.

Domicile as a concept is being abolished under UK law from 6th April 2025.  It is being replaces with a concept of a ‘long-term resident’.

Yes there is a tax treaty between the US and the UK. It’s specific intention is to help taxpayers avoid double taxation. Most types of income and gains are covered by the treaty, but there will be some holes that you should take advice on in order to optimise you tax obligations.

Taxpayers who qualify for the Foreign Income and Gains (‘FIG’) regime can receive certain non-UK income tax free for the first 4 years that they are resident in the UK.  ‘FIG’ is available to UK taxpayers who have been UK tax resident for less than four years, following ten consecutive years of non-UK residence. We can assist you in making this claim correctly.
